| Soil typically includes an organic plant layer, topsoil and layers of minerals, silicates, clay and parent materials. |
| Certain salts, such as the dichromates, borates, and silicates, act as inhibitors to the aqueous corrosion of zinc. |
| Instead, silica is found in polymerized combinations with metals as silicates embedded in geologic rock formations, such as quartz. |
| Moving beyond the Earth to the other terrestrial planets, we find that the rocks there are also dominantly silicates. |
| Soluble silicates can be obtained by heating alkali metal carbonates and silica. |
| The most significant user is the glass industry, which uses sodium carbonate to decompose silicates for glass making. |
